Y j"f O,nrinventiony relates to railway rolling stock andconsists in novellocomotive strucy ture, and particularly in thennderframing i l or bedstructure'ofthe locomotive and in the partsy associated therewith. yvOnefof the objects ofV our invention is to provide `a bed .whichwill'aii'ord the maximum amount of strength for the weight of materialused, and whichwill maintain ,its rigidity fand the positioning of theparts mounted .thereon indefinitely, without the necessity foi-.frequentinspection `and tighteningofIassembledparts. l l Another'objectof-rourlinvention is tov provide abed ,structure having a main'centrall1y located load-,supporting 'Y and longitudiynal-force-transmittingiymember, extending throughout the space abreast of thefdrivers,

and terminating in( spaced yarms extending forwardly ,i and rearwardlyof lthe ,spacer occupied bythe drivers iand serving toltransmitlongitudinalforces to and fromz the centrall member, diagonal splicesbeing' utilized toconnect the central' member and the arms. Preferablythe centralmember, arms and connecting splices will be formedintegrallywith eachother and, lin the selectedoemf bodiment of our;invention illustrated, We

show these parts as :comprising a one piece casting. o

Another object of our invention isto provide afbedfor a locomotivehaving one or morev steam ,cylinders located intermediate the' sidesy ofthe locomotive.` Usually'such' 1ntermediate steam cylinders are formedinte gral with theoiitside cylinder casting r'which yis mounted ontheframeside members and vsecured ,to the outside .orA the latter'jand theheat from the' intermediate cylinder expands 110 the cylinder casting'and tends fte stretch the f bolts or f., other; securing elements,vkthereby loosening the samejand also settinglnp undeysirable strains inthe locomotive bed. `With,

Y o Figu-re a verticalsection, andfFigures 29 and 30 are, respectively, Vtop andy inside side,views illustratingy a modication of our invention; "i i Figure 31 is adet 'section talr'en on vws'statedabove, kronr bed consists preferioo Yablyv of a one piece casting in which the main body portion 1, extendingabreast of the drivers, is of box-shaped cross section throughout mostof its length, although a portionthereof, adjacent the Lmain driver 2,is of inverted U-shape section' in order'toaccommodate the crank arms,counterbalances and connecting rodV for Vthe axle of that driver.V'Vertical lreinforcing*webs 25b are provided or'the inverted U-shapedsection` and connect the bottomY member of the box section backbone withthe horizontal member of the U-shaped section. Extending alongside ofthe backbone member 1 are-side frames 3 which have downwardly projectingportions 4 forming pedestal legs and integral therewith are suitablemembers connecting the legs'oi1 adjacent pedestals and .suitablebrackets for the spring equalizers and other brackets 7 for the brakehangers.

In front of 'the drivers, the main members 8 'of the bed are box-shapedin cross section and are substantially wider than the side frames 3;These side members .8 lare adapted to mount cylinder casting 9 (Fig. 20)and the portions of the members 8 adjacent to the cylinders areconnected'by anintegral horizontal flange 10 which is so close to thesteam cylinder or cylinders 11 located intermediate membersV 8 that itwill be heated to substantially'the same degreea's the cylinder castingwill be heated, and, hence, will *expandl and will spread the sidemembers 8 with the cylinder casting, thus avoiding the tendency toseparat-'e the cylinder casting from its support which would exist ifthe side members were independent ofea'ch other at this point.

l The front ends of member 8 are connected by a front end memberv 12,including a pilot beam. Intermediate of member 12 and'expansion plate10, `each' of the sides is provided with 'a bracket :'13 for mountingvalve gear or other operating structure for the cylinder 11. Eachbracket 13 is separate from the bracket on the opposite side memberwhereby the brackets will not interfere with the spreading yandcontracting of the iside vmember under the influence of expansionplate'lO.

n Adjacent 'j to the pedestal for the front driver,'the`lower portionsof tlie's'i'de frames 3 are connected by a box-shaped tie o'r'crosslmember 14 and the side frames, at4 this point,

e are also provided with brackets lfor supporting themotion plate 16(Fig. 26) rwhich mounts the brackets (one of which is lshown Y at 26)carrying the vcross head guide 27,.

BracketsA 15 are connectedk by an upper cross tie 17 which cooperateswith tie 14 in bracing the bed at this point and serves to maintainbrackets 15 in proper relation toV each other. Theuse of the box-shapedlower tie 14sv and the inverted U-shaped upper tiew17 makes possible theprovision of amplespace between these tie members for accommodating themovement of the center cross head 18.

Each of the side members 8 is p royided with a suitable opening 19 topermit insertion and removal of the; crosshead pin 2O (Fig. 31) and tofacilitate access thereto of a bar, for driving the pin from itsbearings, and nuts for securing the pin. The side members, atfthispoint, a'r'e spaced z ap art 'far u enough to permitthe insertion of thenuts from above,`1i desired; l

A vertical web 25 merges with, the ,inner wall of side member A8adjacent tothe brackets 1 5- and extends .diagonally inwardly Vandrearwardlytherefromto a pointnear the main driverv` reenforcing the mainbackbone memberil. The upperand lower portions ot' web 25'farec'onnectedtothe continuous vertical wall which formsthe inner portion ot' sideAmember.Sand the outerfportion of backbone member'l, as indicated at 25ain Figure 10, thereby forming avbox-ishaped splice for effectivelytransmitting longitudinal, forces the backbone member and the. sidemembs 8. f w'ljhroughout tlieportion kofthe bed abreast of1 thedriv'ersgtheipedestals 'areconn'ected to the outer 'wallet the backbonemember by suitablemembers 28 12, 21, 22, and 23) whereby .the greaterJportion of the vdriving orcesfacting on the pedestals are transmittedto the backbone member'. e The driving forces Aacting on the pedestalsare also transmitted tothe bottom` membermoff the [backbone through. thecross ties connecting thepedestals. e' f Attherear of -thedrivers thesides of the backbone memberdiverge slightly and merge `with thesideframes 3 and with rearwardly extending channel-shaped members29 whichform the sidesof thelocemotivet cradle. The rear :portionofbackbonemember. 1 includes. a vertical `transverse web `33 c urved toextend longitudinally of the bed-and forming with .member 29 abox-shaped section (see Fig. 17

It

will be vunderstood that-fthe other features of i the -bedl aresubstantially Alike `the. preferred construction. These and othermodifications 5 in the details of our bed may be vmade `withoutdeparting from thespirit of our invention, and wel contemplate theveiclusiv'e use of all'sueh variations as come'witlii'n the scope of ourclaims.`
